The XDP OER Series Duramax 6.6L L5P Fuel Contamination Kit XD608 will replace all the debris-riddled parts in the fuel system of your 2017-2021 GM 6.6L Duramax L5P. When the HP4 fuel injection pump fails in your Duramax-powered truck, it often sends debris throughout the entire fuel system.

This results in contamination from the pump that can contaminate the fuel injector lines, fuel lines, and fuel rails, meaning you now must replace all of these parts. Simply flushing the fuel system doesn't guarantee all the lingering metal shavings or contaminants will be eliminated.

This HP4 failure kit is a complete repair solution for your 6.6 Duramax engine with HP4 fuel pump failure, DEF contamination, or water contamination in the fuel system.

This XDP Fuel Contamination Kit XD608 is developed around a high-quality remanufactured HP4 pump and remanufactured stock replacement fuel injectors. This kit also includes a complete set of new fuel injector lines, fuel rails, fuel filter, O-rings, and gaskets.

Replacing these components will help ensure that all debris is out of the fuel system, so you can be sure that the new components don't get contaminated from the previous pump failure.
Features:

  • Fuel Filter
  • Gaskets and O-Rings
  • (2) Fuel Rails
  • (8) Fuel Injector Lines
  • (8) Remanufactured Fuel Injectors
  • (1) HP4 Pump Installation Kit With Fuel Line
  • (1) Remanufactured HP4 Fuel Injection Pump

Note: The core charge on this contamination kit requires that the HP4 injection pump, all 8 injectors, and both fuel rails must be returned for full core credit.

Fitment

  • Will this fit my truck?

    The Fits section at the top of the page lists the manufacturer's applications for this exact part. If your year, make and model is not there, or you are not sure, text us a photo of what you are replacing with your year and engine and we will confirm it before you order.

  • What if I order the wrong part?

    Call or text us before it ships and we will swap it. After delivery you have 30 days to return it in new, uninstalled condition. The return policy has the restocking details.

Shipping

  • When will it ship?

    In-stock parts usually ship within 1 to 2 business days from warehouses across the USA. The stock line under the options tells you the status of the part you are looking at. Large items ship LTL freight and we call to schedule delivery.

  • Why did I only get part of my order?

    We ship from multiple warehouses, so an order with several items can arrive in more than one box. Tracking for each shipment is emailed as it goes out. Full details in the shipping policy.

Returns and warranty

  • What is the return policy?

    30 days from delivery, in new and uninstalled condition, with a restocking fee. Everything is spelled out in the Returns & Refund Policy.

  • How do warranty claims work?

    We are an authorized dealer, so the manufacturer's warranty applies to every part we sell. Call or text us with your order number and we handle the claim with the brand for you.

Paying

  • Can I pay over time?

    Yes. Shop Pay installments are offered at checkout on qualifying orders, and the monthly estimate shows right under the price.

  • What is a core deposit?

    Some remanufactured parts, like injectors and turbos, carry a refundable core deposit. It is shown on the product page when it applies and refunded when your old part comes back to us.
